The outer shroud contacts are the male half — they mate with the matching DF12 receptacle to form a low-profile, high-density interconnect for compact electronics like smartphones, tablets, and portable instruments. The 0.50 mm pitch, 40 positions in 2 rows, and 3 mm stacking height define the fit. Gold plating at 8.00µin on the contacts handles repeated mating cycles. ## Obsolete Status and the Replacement Path For a BOM that needs this exact 40-position, 0.50 mm pitch, 3 mm stack height header, the procurement path is through surplus or broker channels. This header mates with the Hirose DF12 receptacle (the female half) that also specifies a 3 mm mated stacking height. Termination is surface mount — the SMT pads align with the 0.50 mm pitch footprint on the board. The Tape & Reel packaging suits automated pick-and-place assembly lines.","metaTitle":"Hirose DF12E(3.0)-40DP-0.5V(81) Header, 0.50mm Pitch, 40 Pos","metaDescription":"Hirose DF12E(3.0)-40DP-0.5V(81) header, 0.50mm pitch, 40 positions, 3mm stacking height, gold contacts.
